Eros (433) with M31 & M110

Image of Asteroid Eros (433) with M31 & M110. 

Setting: TLAPO80/480 f/6 with flattener and ASI2600MC
Filter: Optolong L-Pro
Camera temperature: -20,7°C
Exposure time: 39x 57s,
Software: SharpCap, ASTAP, CS4, APP (Stellarium & Skysafari)

The flattener was used but with wrong distance: 93 instead of 123mm.



Asteroid EROS (433) my first blink!

Asteroid EROS (433) is almost in opposition and thus perfect for observation.  I had a clear sky with a tempurature of -4,2°C .

Setting: TLAPO80/480 f/6 with flattener and ASI2600MC
Filter: Optolong L-Pro
Camera temperature: -20,7°C
Exposure time: 39x 57s, 
Software: SharpCap, ASTAP, CS4, APP (Stellarium & Skysafari)

Difficulties: connection of mount with Sharpcap was not succesful except for moving the scope. But inaccurate use of goto function and platesolving. It even resulted in miscommunication with the mount. As a result I had to set the synscan back into factory setting. After 3h I was able to make my first image but then I figured out the camera hit the tripod. Once this was solved I made 40 images of which one polluted with an airplane. 
Making sure both Eros and M31 was on my picture, I used stellarium without success. This was resolved with Skysafari.

Sun with Sol'Ex November 8th

A clear sky and enough time for adjusting sharpness. Solution was found in getting the spectrum line in the middle of the space; I get sharpest images when both edges are sharp. Once this was done, I make sure the dustlines on the grating are well seen. 

Setting: TLAPO80/480 with Sol'Ex by James R. and ASI678MM
2nd Gen Slit and Herschel Wedge
Software: SharpCap, Inti V7.0.3, CS4, DeNoise AI
Tilt 0,09°; Sx/Sy 1,09
SSM3 with avg < 1,5arcs whole morning

Saturn with new ASI715MC Camera

First time this year capturing Saturn. The tilt of the rings are almost zero with 0,45°, a Saturn with edge on rings is not the Saturn we typically know from the books. But still interesting view.

I used my new camera ASI715MC with small pixels. I forget to keep an eye on the whitebalance on sharpcap. I made image both with and without IR/UC cut filter.



Compared with my ASI224MC



Setting is same as previous year; it was difficult to get blue/red out even when using my ADC.
